Dehler
Ideal for large-scale ground-mounted PV power plants, rooftop PV systems, and distributed PV projects. It is compatible with various types of PV modules (monocrystalline, polycrystalline, thin-film) and inverters, adapting to different power capacity requirements (from 50kW to 5MW and above).
A photovoltaic (PV) combiner box consolidates the output from multiple solar panel strings into a single circuit before feeding power to the inverter. It reduces wiring complexity, minimizes transmission losses, and houses protection devices such as fuses, circuit breakers, and surge protection devices (SPDs).
The combiner box is compatible with monocrystalline, polycrystalline, and thin-film PV modules, as well as a wide range of inverter brands. It suits ground-mounted utility-scale plants, commercial rooftop systems, and distributed generation projects ranging from 50kW to 5MW and above.
It incorporates multi-layer protection including string-level fuses, DC circuit breakers, and Class II surge protection devices (SPDs). These components isolate faults quickly, preventing damage from short circuits, reverse currents, and lightning-induced surges, keeping both equipment and personnel safe.
Yes. The intelligent combiner box provides real-time monitoring of key parameters such as string current, voltage, and temperature. Remote fault diagnosis capabilities allow O&M teams to identify and address issues promptly without on-site inspection, improving overall system uptime.
The combiner box is engineered for a service life exceeding 25 years, matching the operational lifespan of standard PV modules. This is achieved through a rugged IP65-rated enclosure, high-quality internal components, and corrosion-resistant materials suitable for outdoor environments.
By consolidating multiple PV string outputs, the combiner box can reduce the number of cables running between the PV array and the inverter by up to 70%. This significantly cuts material costs, labor time, and ongoing maintenance expenses.
